If a child develops encephalitis, it is definitely recommended that they be hospitalized for treatment. It is necessary to assess their condition and determine the cause of the encephalitis: is it viral? Bacterial? Or caused by other pathogens? If encephalitis occurs, aggressive treatment is certainly required. In such cases, if the child is discharged from the hospital, they must regularly revisit the hospital for follow-up examinations, and the development of the child's nervous system must be monitored, focusing on motor and cognitive development. Regular assessments at the hospital are definitely required.

What is checked for encephalitis?

The examination items for encephalitis mainly include, first, some basic hematological tests. These include routine blood tests, liver and kidney function tests, electrolytes, etc., to understand the status of the patient's white blood cells and whether there is any damage to liver and kidney functions. It is also necessary to test for cardiac enzymes, as some viruses can also affect the heart. Second, an EEG is required. Abnormal EEG patterns, such as increased diffuseness, can be observed in encephalitis, which is important for accurate diagnosis. Third, further examinations like lumbar puncture and cerebrospinal fluid tests are needed. The main focus in cerebrospinal fluid is to see if there is an increase in white blood cells and to check if there are any changes in protein and sugar levels in the fluid. This has great reference value for diagnosing whether it is encephalitis and what type of encephalitis it might be. Fourth, a cranial MRI can be performed to clearly identify if there are any organic lesions in the brain.

Does encephalitis require hospitalization?

The severity of encephalitis can vary greatly; it is generally caused by viral infection. Among these viruses, Herpes Simplex Virus (HSV) is particularly dangerous. Encephalitis caused by HSV can be very severe, with symptoms including high fever, headache, nausea, vomiting, and other serious manifestations. Some patients may even experience seizures, coma, cognitive decline, and changes in mood and behavior. This type of encephalitis is very severe and definitely requires hospitalization. Typically, hospitalization lasts about 2 to 3 weeks, and proper antiviral treatment is necessary. Additionally, there are other forms of encephalitis caused by different viruses that are relatively milder and may even have a certain degree of self-healing properties. Generally, resting well, drinking plenty of water, and consuming fresh vegetables and fruits can lead to recovery. Therefore, whether hospitalization is necessary for encephalitis depends on the severity of the condition and the assessment of which virus has caused the infection. It cannot be generalized.

What tests are conducted for encephalitis?

First, it is generally necessary to conduct an EEG test. This test is very convenient and non-invasive for patients. If significant slow waves are detected, encephalitis cannot be ruled out. Secondly, an MRI of the brain should be performed. If the viral encephalitis is severe, abnormal signals can be observed in areas such as the frontal lobe, temporal lobe, and hippocampus on the MRI, which are of great diagnostic reference value. Thirdly, lumbar puncture is also very important. It allows for a direct observation of the color of the cerebrospinal fluid, to monitor the pressure of the brain fluid, and to test the cerebrospinal fluid for cell count, protein, sugar, and chloride levels. These tests are very important for the diagnosis and differential diagnosis of encephalitis.

Symptoms of encephalitis vomiting

Patients with encephalitis often experience vomiting, and some even have projectile vomiting. This is mainly because patients with encephalitis experience a significant increase in intracranial pressure, which leads to severe vomiting. Additionally, patients may also have noticeable fever, headaches, and can display swelling of the optic disc. In such cases, it is necessary to promptly administer sufficient antiviral medications to the patient, as well as some medications to dehydrate and reduce intracranial pressure. If necessary, corticosteroids can also be used as an adjunct treatment. With aggressive treatment, some patients do recover well. (Please administer medication under the guidance of a professional physician.)

Symptoms of baby encephalitis

Generally speaking, the symptoms of encephalitis in babies usually start with fever. Encephalitis is an infectious disease, and the majority of cases present with fever, which could be either high or low. Next is vomiting. Since small infants cannot express headache, they usually manifest symptoms through crying, irritability, and restlessness. Additionally, there might be lethargy and malaise. Some may experience seizures, and others might have stiff neck, characterized by rigidity of the neck and changes in muscle tone of the limbs, among other symptoms. These are all symptoms of encephalitis.
